Can you describe it a bit more?
Jeff - What style bulb is it? Screw in? Twist style with one bottom element? Two bottom elements? Also, could you identify the fixture itself? Lots of people make bulbs, so finding a match shouldn't be too hard. If there is a decent marine store near you, take the bulb over and try to match it. Voltage and wattage (CP is essentially going to give you wattage, though the corelation isn't perfect) with style will get you there.Justin - O'day Owners' Web
